I wrote this to keep my WebBot up-to-date. Someone can port this to Win32 batch if they want, but I'm too lazy. Could simply be a simple rename and a download of a few GNU tools. Again, too lazy to try. I run my WebBot from Linux using Wine, so eh..
echo "WebBot Auto Updater by Joe[x86]"
wget -q http://botdev.valhallalegends.com/files/webbot.zip
unzip -qo webbot.zip
rm webbot.zip
echo "Your WebBot installation is up-to-date!"
